State-Changed-Why: 
Vladislav,
w/o a backtrace or any other information, it's quite hard to tell where
the problem might come from.

Your screenshot suggests, there's a NULL pointer causing the trouble.

Can you please try at first the following command and post us it's output:
addr2line -e /boot/kernel/kernel.symbols 0xffffffff806aa114

If your kernel config is near GENERIC, the problem might be in
sys/net80211/ieee80211_node.c:2328

Having a backtrace would make things simpler. If you're brave enough, you
may try to get the kernel dump onto a usb thumb drive (I'm using this for
embedded machines, where I don't have the space to store dumps).
It works find, just take a look at dumpon(8).

If you got a dump, please use the kernel debugger to get the backtrace.
